standpipes, and to provide means whereby said communicationmay be established or disestablished together with means for keeping the standpipes clear.

In the drawing: e V

Figure 1 is a view in elevation with parts in section of the deviceassembled,

Fig. 2 is a side elevation of the upperpor- 1 tion, of the stand pipe with parts thereof broken away and parts thereof shown in section, and

Fig. 3 is another side elevation of the sta'ndpipe, taken at right angles to the view shown in Fig. 2.

The lower end of the standpipe 1, enters a trough 2, which is provided at one side with an outlet opening A septum wall 0. or battle 4 is arranged transversely across the trough 2, at a point spaced from the outlet opening 3. The upper edge of the wall 4 is disposed in a plane above the plane, in which the lower end of the standpipe 1 lies. The trough 2 may retain a volume of water,

the level of the surface of which will be at the level ofthe upper edge of the wall '4, and whereby the lower end of the standpipe 1. is closed or sealed, by the volume of water retained in the trough. Any water in excess of such amount will flow over the upper edge of the sealing battle 4, and make its exit from the trough 2 through the outlet opening 3 thereof,

Atintervals along its vertical height, the standpipe 1 is provided with openings 5, which are normally closed by flexible plates 6. By removing the plates 6, the interior of 3 mechanism the standpipe 1 may be gotten at, for the purpose of cleaning, or for removing obstructions therefrom, or forarranging the and means located thereine Thimbles 7 penetrate the side of the standpipe 1, at vertically spaced intervals, and eachthimble may be connected with. aretort. Shafts 9 are disposed transversely across the standpipe 1, at points below the lower edges of the thimbles'T. Each shaft 9 is provided with an arnilO, which carries a plate valve l1, and this plate valve may close against the inner end of one of the thimbles 7, as best shown in Figure 2 of the drawings. Handles 12 are applied to the ends of the shafts 9, and are located exteriorly of the standpipe 1, and may be used for turning the said shaft-s to move the plate valves 11 over the inner ends of the thimbles or to move said valves away from the said thimbles.

For washing or scrubbing the gases which accumulate in astandpipe, during the operation of the, retort, while producing gas, a cap 13 is provided, and is applied to the upper end of the stand pipe 1. A pipe 14 passes centrally through the cap 13, and is connected with a seal 15, the terminal fold of which is provided with a funnel 16, which is upwardlydisp sed and in wliichwater may bepoured from the supply pipe S, for the purpose of feeding the same through the manifold, into the pipe 14, and permitting the water to pass through the standpipe 1. A spreader 17 is connected with the pipe 14 and has an end portion disposed below and spaced from the outlet end of the pipe 14. The said spreader is located within the standpipe 1, and the stream of water which fallsfrom thepipe 14 strikes the spreader 17 and is broken into a number of fine streams, or is separated in the form of drops, and these drops or streams descend through the gases, which have accumulated in the standpipe, washing the same, and carry the carbon and particles of solid matter, into the trough 2. Thus these gases are scrubbed, and during the process of producing the gas in the retort, one or more of the ret-orts may be cut oil from the standpipe by closing the valve or valve plate 11, and at such time, the said retort may be discharged and recharged in the usual manner.

A dip pipe 20 is in communication with the standpipe 1 and leads into an ordinary hydraulic main H for permitting the gas to flow from the standpipe.

Having described the invention, what is claimed is; i

In apparatus for the manufacture of gas, the combination of a plurality of retorts, a stand pipe, means for establishing anddisestablishing communication between the retort and the standpipe, a trough receiving the lower end of the stand pipe, a cap applied to the upper end of the stand pipe, a pipe passing through said cap, and a spreader carried by the last mentioned pipe and having an end portion disposed below and spaced from the lower discharge end 20 thereof.

In testimony whereof I aflix my signature.
